title: Staging and assessing trophoblastic tumors. A possible solution to an intractable problem.
abstract: The present situation of staging gestational trophoblastic tumors by the system of the International Federation of Obstetrics and Gynecology (FIGO) and of scoring systems of risk factors in such tumors is examined critically. A solution for resolving staging and scoring difficulties is offered by combining the present FIGO staging with the accepted standardized World Health Organization system.
